Right answer. There is indeed an internal separator in the reservoir. If the fluid runs low while you're pumping out the rear brake, the reservoir will LOOK full, but it isn't. After a few strokes, you'll be pumping air. When I'm bleeding rear brakes I keep the reservoir filled to the brim, then suction out any excess after I'm done.

Ahh rats. So do you think that I need to re-bleed the master?

EDIT: Just re-read this and understood it better. I definitely never went that low in the reservoir -- I think that the most that i ever let the fluid drop was 1/5 of the way from full to empty.

I'll probably start WW3 by saying that bench bleeding is a waste of time. But it is!
